Crosman 1377 Steel Breech Riser

This is a printable breech riser for the Crosman steel breech.

The included STL is a 5mm riser.

You can customize the riser height in the SCAD. You can also tweak the hole diameters also. 

Keep in mind you will need a longer hammer pin for cocking, and longer screws: the rear is an 8-32, and the tiny one in the loading port is a 4-48.
